I was at Peking Village for dinner tonight in the same shopping center as the not-yet-open Great Wall Chinese supermarket. While there, we asked the waitress if she knew when GWC would open. According to her, it will be open in three weeks, so in early August I'll check again.
Incidentally, Peking Village was still up to its previous level of quality, so if anyone is looking for authentic Sichuan, closer to town (marginally) than China Star, this is still an option. (But make sure to get the Chinese menu, which is now printed on yellow rather than green paper.)
